In a pinch you would probably be better off with no gasket and just using gasket maker on both the block and the manifold. 20 years ago that was all the rage and everyone was preaching about how great it was. I never bought into it, always had great success with Felpro and Permatex 2B sealant. If it was something skitchy, I'd use 3-M gorilla snot with the Fel pro gasket.
But if I was 2 weeks out on parts and needed to get my car runing, I would get the block super clean, then wipe it down with some alcohol or solvent. After it dries for a few minutes, put a bead of gasket maker on the block, then a bead in the same spot on the manifold. iI may help to put a light bead on the block, then lightly set the manifold on and then pull it off. That way the silicon while mark the exact spot on the manifold.
Re-apply the light bead on the block and on the manifold and then let it sit out for about 20 minutes. Then install together. Criss cross inside out tighten the manifold and wipe off any excessive bleed out. DO NOT OVERTIGHTEN! You have no gasket and an aluminum manifold on a steel block, so you could easily snap that manifold. I would tighten snug, but I wouldn't torque it down.
I wouldn't keep this as a permenant fix, but like I said, if I were 2 weeks away from parts, and needed my car running, I would order the correct gaskets, do this and then when I got the gaskets, tear it down, clean it up and do it the right way.
